1 pound (454 grams) of Trehalose. HINT! Ordering 12 pounds each is the most economical option due to shipping costs (limit is 12 pounds per order). Trehalose is a unique sugar found in many types of plants and insects. PLEASE NOTE: Trehalose can be a problem in the case of two different types of Clostridium difficile infection, if you are exposed to these strains and are otherwise susceptible. At the very least, any person who is suffering from a C. difficile infection should consider eliminating trehalose from their diet for the duration of the infection.
